rf power out

I just got the radio back from service due to a blown U5. On AM/FM/USB/LSB I have good power out as shown by the SmartSDR program and the amp meter on my power supply. Using the FM mode when I key the radio I show 100 watts RF out and the PS shows about 20 amps.

However, when I try digital modes the program shows no power out and the amp meter on the power supply only shows about 5 watts of power used.

The RF power slider is set to max and my SWR is about 1.25 : 1 through the radios tuner to my 80M loop.

Before I sent the radio in for the blown U5, the digital modes had good power out as shown by both the program and the PS.

Mike, I have a level shown in the DAX control panel TX stream that is almost full scale. I show very little change in the radio level. Nothing like it was before sending the radio in.

Shut down DAX, SSDR and WSJT-X. Restarted them all. Still the same. I show almost full scale in the DAX control panel, not very much in the radio level. I am using FT8 mode and the isn't anything that shows audio level for that in the program.

I've had the same thing happen to me twice in the past 2 weeks. Each time the problem is fixed by shutting down DAX and restarting it. Just closing SSDR and restarting does not help. I had to close the DAX panel and restart it. This happened while I was using WSJT-X for FT8

Since the later releases of V1 and now V2 ,I have removed both DAX and CAT from the computer start- up menu. Now I use this procedure: Boot up the computer and let it stabilize. Then start DAX followed by CAT and make sure they are running. Then start SSDR. Since using this procedure I have had no DAX , CAT failures or disconnects. This works for me on both laptop computers. DAX and CAT must be removed from start-up for each new release of SSDR. Might be something to try.
